Detailed Description

Logging backend that writes to an Intel ADSP mtrace SRAM buffer.

Typedef Documentation

adsp_mtrace_log_hook_t

typedef void(* adsp_mtrace_log_hook_t) (size_t written, size_t space_left)

#include <log_backend_adsp_mtrace.h>

mtrace logger requires a hook for IPC messages

When new log data is added to the SRAM buffer, a IPC message should be sent to the host. This hook function pointer allows for that.

Function Documentation

adsp_mtrace_log_init()

void adsp_mtrace_log_init

(

adsp_mtrace_log_hook_t

hook

)

#include <log_backend_adsp_mtrace.h>

Initialize the Intel ADSP mtrace logger.

Parameters

hook	Function is called after each write to the SRAM buffer It is up to the author of the hook to serialize if needed.

log_backend_adsp_mtrace_get()

const struct log_backend * log_backend_adsp_mtrace_get

(

void

)

#include <log_backend_adsp_mtrace.h>

Get the Intel ADSP mtrace log backend.

Returns

Pointer to the mtrace log backend instance.
